playing music in MP3 app messed up project bitrate

I opened up a wav file in another app, and cubase detected a bitrate change and my whole project became messed up, and I’m not sure how to recover. Some files are playing fast, midi is unsynced with audio and everything is a huge mess.

What is the quickest way to recover this?

reset your interface to the correct sample rate in it’s control panel

I did that, and everything is totally jacked up, some tracks are faster, some slower. Not sure what I need to do here.

Are you absolutely certain the sample rate in interface is the same as set in your project??
This is the most likely problem unless you changed tempo by mistake or something.

Maybe try a restart.
